And the state of Washington keeps a list, last updated in 2011, which has seven state highway bridges in Snohomish County categorized as structurally deficient. Structurally deficient doesn’t mean unsafe. It means it’s time for repair or replacement. Two of those state-managed bridges have since been repaired or replaced.

Four of the seven bridges serve the short but busy stretch of Highway 529 between Everett and Marysville. One of those, across Ebey Slough, has recently been replaced.
